Hi! I discovered that a raccoon got into our coop one night and took a young silkie. No body, but feathers everywhere, up the fence where the coon climbed, and feathers in a tree nearby. We have since secured the coop at night. However, the chickens are in an 8 foot high chain link run during the day. Tonight when I did a head count, I found that I'm missing an adult silkie and a full grown Dominique. The chickens could not have gotten out on their own, and we have no stray dogs. What could this be? There's no evidence, either. Thanks!
